Abstract (en)
[origin: EP0385120A1] An asymmetric dioxazine compound of the following formula in the free acid form, <CHEM> wherein R is hydrogen, halogen, sulfo or alkoxy, R1, R2 and R3 are each hydrogen or alkyl, X1 and X2 are each hydrogen, halogen, alkyl, alkoxy or phenoxy, Y is alkylene, phenylene or naphthylene, Z is -SO2CH=CH2, -SO2CH2CH2OSO3H or the like, V is hydrogen, alkyl, acyl or substituted triazinyl, and Q is halogen, alkoxy, amino or a group similar to that of <CHEM> provided that R is hydrogen, and Q is amino or a group similar to that of <CHEM> when V is substituted triazinyl, which is useful for dyeing or printing fiber materials to give dyed or printed products of a brilliant blue color superior in fastness properties, particularly those such as chlorine fastness with superior build-up property.
